Abstract

1406797 Disazo pigment HOECHST AG 18 Jan 1974 [19 Jan 1973] 02419/74 Heading C4P The disazo pigment of the formula in a form characterized by a specific surface of 12-30 m.<SP>2</SP>/g., a grain size distribution with a maximum within the range 250-500 nm, and the proportion of grains having a size of from 250 to 500 nm in the total distribution being 35-65 % is prepared by heating the pigment obtained after coupling Specification 441,091 at above 100‹ C. in a solvent which is immiscible with water or is miscible to a maximum of 20 g. per 100 g. of water. Suitable solvents include halogenated aromatic compounds, C 4-8 alcohols, aromatic nitro compounds, aromatic amines, aromatic ethers, esters of aromatic acids and ketones. The solvent may contain water. The pigment is especially suitable for the pigmentation of stove lacquers, plastics and special printing pastes.
